Question

Suppose a ball is thrown straight up into the air, and the height of the ball above the ground is given by the function h(t) = 6 + 37t – 16t2, where h is in feet and t is in seconds. At what time t does the ball stop going up and start returning to earth?

Answer 1

you are given h(t), to you need to take the derivatave of h'(t) and set it to zero.
The derivative of height is velocity.

Answer 2

Ohhhhhhhhhhhhhhhhhhhhh, Thanks!

Answer 3

37 - 32(3.2) = -65.4
